WINDOW-FASTENER.

Specification of Letters Patent.

Application filed May 15, 1913.

Patented Apr. 21, 1914.

serial No. 767,792.

T 0 all whom it may 0011067177J Be it known that I, Louis BAUER, a citizen of the United States of America, residing at New York city, borough of the Bronx, county and State of New York, have invented certain new and useful Improvements in Vindow-Fasteners, of which the following is a full, clear, and exact description.

This invention relates to an improvement in window fasteners.

The improvement also embodies a catch that prevents the upper sash being lowered.

My improved device is designed to be set into the rabbet or groove, in the window frame, in which the lower sash slides.

Other features of improvement will hereinafter appear.

I will now proceed to describe my invention in detail, the novel features of which I will point out in the appended claims, reference being had to the accompanying drawing, forming part hereof, wherein Figure 1 is a fragmentary face view of a window frame and sashes, the sashes being shown in section, having my improved device attached thereto; Fig. 2 is an enlarged face view of my improved alarm device; Fig. 3 is an enlarged vertical sectional view thereof, the section being taken on a line 3-3v in Fig. 2; Fig. l is a cross sectional plan view of the alarm frame and slide, the section being taken on a line 4 4 in Fig. 2; Fig. 5 is a fragmentary detail view of the rear side of the slide, showing the releasing pin; Fig. 6 is an enlarged detail view of the slide-look operating lever; and Fig. 7 is an enlarged sectional view thereof, the section being taken on a line 7 7 in Fig. 2.

As herein illustrated, my improved alarm comprises a frame 1, a slide 2 carried thereby, a lock 3 for the slide, a lever 4L for actuating the lock, a bell 5 and a pointed catch 6 for engaging the side member of the upper sash of the window. In connection with the lever t, I employ a link 7 which connects the lever t and lock 3. To cause the bell 5 to ring I employ a releasing device or slide 8 which is actuated by the movement of the lower sash. As can be seen in Fig. 1, the alarm is located in the rabbet 9 in which the sash 10 slides, the slide 8 resting upon the said sash. When the alarm is in this position, the catch 6 will rest in contact with the sash 11, it being kept in contact with the sash by a spring 12.

By referring to Fig. 4C, it will be seen that the frame or support 1 is provided with a flange 13, and the slide 2 with a flange 14, said flanges being designed to contact with the side walls 15 and 16 of the rabbet or groove 9. The alarm is held in position in the said rabbet or groove by means of the lock 3 which, after the alarm has been positioned in the groove, will be forced downwardly, to contact with the slide, by the le` ver 4 and link 7. After the lock has engaged the slide, it will be moved ahead, carrying the slide with it, which movement will force the slide against the wall 15,`and jam the shoulder 13 against the wall 16.

To impart movement to the lock and slide, I employ an eccentric block 17 which is carried by the plate 1a on the lever 4, and works in an opening 19 in the link 7. A pivot screw-pin 2O secures the lever A, and plate 4i to the frame or support 1. (See Fig. 7

To impart a downward movement to the lock 3, when moved in one direction, and an upward movement when moved in the opposite direction, I employ cam-slots 21 through which pins 22 pass into the frame 1 and slidably secure the said lock to said frame. The slide 2 carries a block 23 provided with teeth 24 with which the teeth 25 on the lock 3 mesh. To prevent the lever from crossing the dead center, when moved to actuate the lock and slide, I employ a stop-pin 26, (se-e Fig. 1). To facilitate the releasing of the slide when it becomes desirable to take the alarm from the window, I employ a pin 27 backed by a spring 28. When the slide 2 is forced in contact with the window frame, the spring 27 will be placed under tension, and when the lock 3 is released or caused to leave the slide, the reaction of the spring 28 will force the slide away from the wall of the groove 9, thereby obviating the necessity of pushing the slide with the fingers.

The bell 5 is an ordinary bicycle-bell which, when the pin 29 is forced inwardly, will ring. To actuate the pin 29, I employ the slide 8.

When the alarm is in position, as shown in Fig. 1, the sash 11 cannot be lowered due to the catch 6, and should an attempt be made to raise sash 10, the slide 8 would actuate the pin 29, and the bell will ring, at the same time prevent-ing the lower sash from being raised.

While I have shown and described an alarm associated with the window fastener, it is to be understood that I make no claim thereto Having now described my invention, what I claim and desire to secure by Let-ters Patent is:

l. A Window fastener consisting of a support adapted to fit the groove of a window frame, a slide adapted to hold said support in position, a spring-pressed releasing-pin carried by said slide, a lock for said slide, means to actuate said lock, a catch adapted to engage a window sash.

2. A Window fastener consisting of a support adapted to t the groove 0f a Window frame, a slide adapted to hold said support in position, teeth carried by said slide, a slidable lock, teeth carried by said lock adapted to mesh with the teeth on said slide, a lever for actuating said lock, a link connecting said lever and lock, a cato-h carried by said lever adapted to engage a window sash.

3. A window fastener, consisting` of a support adapted to iit the groove of a window frame, a slide carried by said support adapted to hold said support in position, a lock for said slide, a spring pressed releasing pin carried by said slide, a lever to actuate said lock, and a catch carried by said levzr adapted to engage the other windowsas i.

4. A window fastener 'consisting of a sup port adapted for attachmentto a windowframe, a serrated slide adapted to hold said support in position.I a slidable lock adapted to engage the serrations on said slide, said slide being provided with cam-slots, pins passing through said slots and into said support, and a lever adapted to actuate said lock, and cause it to move downwardly to engage said slide and t-o actuatc the same.

Signed at New York city, N. Y., this 13th day o-f May, 1913.
